## Background
BACKGROUND OF THE INVENTION
The present invention relates to open office plans and the like.
The efficient use of building floor space is an ever-growing concern, particularly as building costs continue to escalate. Open office plans have been developed to reduce overall officing costs, and generally incorporate large, open floor spaces in buildings that are equipped with modular furniture systems which are readily reconfigurable to accommodate the ever-changing needs of a specific user, as well as the divergent requirements of different tenants. One arrangement commonly used for furnishing open plans includes movable partition panels are detachably interconnected to partition off the open spaces into individual workstation and/or offices. Such partition panels are configured to receive hang-on furniture units, such as worksurfaces, overhead cabinets, shelves, etc., and are generally known in the office furniture industry as “systems furniture”. Another arrangement for dividing and/or partitioning open plans includes modular furniture arrangements, in which a plurality of differently shaped, freestanding furniture units are positioned in a side-by-side relationship, with upstanding privacy screens attached to at least some of the furniture units to create individual, distinct workstations and/or offices. Both of these types of modular furniture systems, as well as others, have been widely received due largely to their ability to be readily reconfigured and/or moved to a new site, since they are not part of a permanent leasehold improvement.
At present, some types of furniture systems utilize vertical rows of slots to support hang-on furniture units. Also, systems have been developed that utilize horizontal rows of slots for supporting hang-on furniture units such as storage units, worksurfaces and the like. Existing furniture systems commonly include cover panels that are attached to a partition frame to close off the frame and provide visual and audio privacy for the worker. However, existing furniture systems may not provide sufficient flexibility to permit the location of the hang-on furniture units to be readily adjusted. Furthermore, positioning of the cover panels on existing systems may be problematic.
Considerable efforts have been made to provide the users of such furniture systems with power and/or data connections for users of the system. Existing systems typically include worksurfaces that are utilized to support various accessories such as phones, computer monitors, printers and the like. In general, the worksurfaces must be relatively large to support such equipment, such that the overall size or “footprint” of the workspace for a given user will be quite large. The relatively large footprint requires more floor space, leading to more cost per user.
SUMMARY OF THE INVENTION
One aspect of the present invention is a freestanding partition panel for dividing a floor space. The partition panel includes a rigid partition frame having horizontally spaced apart vertical side frame members and vertically spaced apart first and second horizontal frame members extending between the vertical side frame members to form a generally quadrilateral vertically enlarged opening through the frame, and defining an open space within the panel. The partition panel includes at least one intermediate horizontal cross member extending across the vertically enlarged opening and defining an upper opening through the frame above the intermediate horizontal cross member, and defining a lower opening through the frame below the intermediate horizontal cross member. The intermediate cross member and at least a selected one of the first and second horizontal frame members include a plurality of horizontally spaced apart attachment locations defining a plurality of discrete, serially adjacent mounting spaces in a selected one of the upper and lower openings through the frames within the open space. The partition panel further includes a utility unit connectable to selected ones of the attachment locations of the intermediate horizontal cross member and the selected one of the first and second horizontal members, such that the utility unit can be mounted in a selected one of the mounting spaces. The utility unit has a side edge spaced apart from a selected one of the vertical side frame members. The partition panel further includes a first cover panel secured to the partition frame and extending horizontally between the side edge of the utility unit and the selected vertical side frame member. The first cover panel is connected to the intermediate horizontal cross member and extends vertically between the intermediate horizontal cross member and the selected one of the first and second members. A second cover panel is secured to the partition frame, and extends horizontally between the vertical side frame members. The second cover panel extends vertically between the intermediate horizontal cross member and the other of the selected one of the first and second members.
Another aspect of the present invention is a freestanding partition panel for dividing floor space. The partition panel includes a rigid partition frame having first and second horizontally spaced apart vertical side frame members, and elongated vertically spaced apart first and second horizontal members extending between the vertical side frame members to define an open space within the panel. The first and second horizontal members include a plurality of horizontally spaced apart attachment locations defining a plurality of discrete, serially adjacent mounting spaces within the open space. A utility unit is connectable to selected ones of the attachment locations of the first and second horizontal members, and extends vertically between the first and second horizontal members. The utility unit defines a generally vertical side edge that is horizontally spaced apart from the first vertical side frame member to define a gap therebetween. A cover panel is secured to the partition frame, and has a first vertical side edge proximate the vertical side edge of the utility unit, and a second vertical side edge proximate the first vertical side frame member. The cover panel is secured to the first and second horizontal members and extends therebetween to substantially close off the gap.
Yet another aspect of the present invention is a method of configuring a partition panel. The method includes providing a freestanding partition frame defining horizontally spaced apart vertical side faces and an interior space between the vertical side faces. The partition frame has first and second generally vertical side edges that are horizontally spaced apart to define a frame width. The partition frame has generally horizontal upper and lower edges defining a generally quadrilateral perimeter with the vertical side edges. The method includes dividing at least a portion of the interior space into a plurality of serially adjacent mounting spaces defining a horizontal row. The mounting spaces each have substantially the same size and configuration. A plurality of utility units is provided, each configured to be mounted into a selected one of the mounting spaces at a selected horizontal position. The utility units have an exterior side surface that faces outwardly, and a generally vertical side edge and generally horizontal upper and lower side edges defining a height. The utility unit is secured to the partition frame in a selected one of the mounting spaces at a selected horizontal position with the vertical side edge of the utility unit spaced inwardly from the first vertical side edge of the partition frame to form a first gap defining a width that is substantially less than the frame width. The upper side edge of the utility unit is spaced downwardly from the upper edge of the partition frame to form an upper gap having a width about the same as the frame width. The lower side edge of the utility unit is spaced upwardly from the lower edge of the partition frame to form a lower gap having a width about the same as the frame width. A first cover panel having a width substantially equal to the first gap is provided. The first cover panel has a height substantially the same as the height of the utility unit. The first cover panel is installed to the partition frame to substantially close off the first gap. An upper cover panel is installed to the frame to substantially close off the upper gap, and a lower cover panel is secured to the partition frame to substantially close off the lower gap.
Yet another aspect of the present invention is a flat display screen for mounting to partitions. The arrangement includes a flat display screen adapted to provide images. First and second support arms each have first and second links pivotably interconnected. Each first link has an end adapted to be pivotably mounted to a partition for pivoting about a substantially vertical axis. Each second link has an end pivotably connected to the display screen, and the first and second support arms support the display screen for movement in the horizontal direction between a stored position and a use position.
These and other features, advantages, and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following written specification, claims, and appended drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
The present application is related to co-pending patent application Ser. No. 10/077,553 entitled PANEL SYSTEM, filed on even date herewith, the entire contents of which are hereby incorporated by reference.
For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in FIG. 1. However, it is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
The reference numeral 1 (FIG. 1) designates a partition system 1 including a plurality of partition panels 2. Each of the partition panels 2 includes a partition frame 3, each of which may include one or more intermediate beams 4, and one or more cover panels 6. One or more modular appliance units such as a flat screen monitor 7, power module 8, or storage module 9 may be mounted to the intermediate beams 4 and/or horizontal frame members 13, 14 at a selected horizontal location. In addition to the full width “segmented” cover panels 6, one or more smaller width cover panels 10 may be utilized to close off the gap that would otherwise exist adjacent the modular accessory units 7, 8, and 9. Cover panels 10 have the same height as the modular accessory units, and a width as required to close off the gap between the vertical side edge of the modular accessory unit and an adjacent vertical frame member 12. If required for a particular application, a plurality of modular accessory units may be mounted to the frame in a side-by-side manner extending across the entire width of the frame 3, such that smaller cover panels 10 are not required. Although the modular accessory units 7, 8 and 9 are illustrated as being positioned at the same height, as described in more detail below, the accessory units may be positioned at various different heights as required by the user.
In addition to the flat screen modular accessory unit 7, power and data modular accessory unit 8, and storage modular accessory unit 9, additional modular accessory units may be utilized to provide a wide variety of features to enhance the work environment. Various modular accessory units according to the present invention are illustrated in FIGS. 1A-1AE. The modular accessory units may comprise various high tech devices to facilitate data flow through the adjacent work areas and the like. Other electronic modular accessory units may be utilized to control the temperature, noise, or other environmental conditions within the work area to thereby optimize a user's comfort and productivity. A modular appliance unit comprising “Polycom”—style voice conferencing system 1A suitable for small group space is illustrated in FIG. 1A, and an integrated Plantronics-style wireless headset 1A that reduces clutter from around the phone is illustrated in FIG. 1B. A small touchscreen appliance 1C for the communication of graphic, video and audio data is illustrated in FIG. 1C, and a modular accessory unit with an integrated, vertically oriented printer 1D for personal printing is illustrated in FIG. 1D.

A wall-mounted speaker 1F with controls 2F is illustrated in FIG. 1F. The horizontally and vertically selectable mounting arrangement of the modular appliance units permits optimal positioning of the speakers 1F in the workspace.
Various network hubs may be utilized to provide a common connection point for the devices on the network. The hubs provide information sharing a distributed feedback. These appliance units can be selectively mounted at an optimum vertical and horizontal position without cluttering the workspace. A modular accessory unit comprising an integrated OEM Bluetooth, 802.11, or other wireless networking hub 1G is illustrated in FIG. 1G. The distribution of this hub is based on coverage area and the number of devices in use. The bluetooth unit may be mounted adjacent the upper edge of the partition to properly position the antenna. An infrared network hub is illustrated in FIG. 1H. The IR hub may be mounted at a central height to provide line-of-sight access to peripherals. A USB hub 1I with integrated cable management is illustrated in FIG. 11. A status indicator 1J for phone, privacy, voicemail, etc. is illustrated in FIG. 1J. The status indicator is positioned at the upper edge of the partition panel, and a light or the like indicates a phone-in-use condition to others in the area. FIG. 1K shows a passive-infrared motion detector that may be operatively connected to an alarm system, lighting control, and occupant status and location information. A thermometer and thermostat for controlling local heaters and fans to provide an optimal work environment is illustrated in FIG. 1L. A modular accessory unit comprising a distributed temperature sensor with display is illustrated in FIG. 1M. The distributed temperature sensor provides for control of the HVAC system within the office area. An infrared control/light switch for overhead lighting is illustrated in FIG. 1N. The lighting system used with the IR control is outfitted with an IR receiver, and implicit zonal control of the overhead lighting system can be achieved by modifying the shape of the IR beam. Still further, a tip-out lighting fixture to provide both task and ambient light is illustrated in FIG. 1O. The tip-out lighting fixture may be a low-voltage halogen unit providing optimum lighting conditions on the worksurface without cluttering the worksurface. With reference to FIG. 1P, a small space-heater 1P with an integrated thermometer may be utilized to provide consistent temperature control within the work area. Louvers for directing the flow, a control for the speed, and optional remote temperature sensor and/or control is also illustrated in FIG. 1P. The space-heater may be a two way beater providing heat to both sides of the partition. The modular mounting feature permits positioning of the heater at an optimal location, such as directly below the worksurface or adjacent the lower edge of the partition. A fan to provide airflow directed at the occupant and louvers to control direction/flow rate is illustrated in FIG. 1Q. The fan is preferably capable of providing slow airflow, and may be mounted above the worksurface.
Other modular accessory units according to the present invention facilitate routing, access, and management of utility lines in the work area. A slatwall support surface 1R with translucent tilt-away section 2R for access to power and/or data receptacles positioned within the partition panel is illustrated in FIG. 1R. The slatwall facilitates utilization of space behind the surface. A cable trough IS for management of peripheral cables 2S and the like within the beltway 3S is illustrated in FIG. 1S, and a storage cabinet IT with a pivotably mounted whiteboard door surface 2T is illustrated in FIG. 1T. The storage cabinet provides convenient, private storage of personal items such as medicines, keys, and the like, as well as office items. With reference to FIG. 1V, the modular accessory unit may comprise a storage unit 1U with a clear panel 2U for display purposes. Various personal or decorative items may be placed in the storage unit for display to personalize the work area. A secure storage cabinet 1V with lockable door 2V and adjustable shelves 3V is illustrated in FIG. 1V. A modular accessory unit comprising a receptacle 1W for papers, magazines, and the like is illustrated in FIG. 1W, and a “mail-slot” modular accessory unit 1X is illustrated in FIG. 1X. A retaining member 2X is pivotably mounted at the lower portion thereof to permit pass-through of papers 3X or the like between co-workers or from a public to a private space.
Various other types of modular appliance units may also be utilized to control, monitor and/or restrict access and/or privacy between adjacent workspaces as required for a particular application or office environment. For example, a small window providing visual and aural access through the panel is illustrated in FIG. 1Y. With reference to FIG. 1Z, a small window 1Z provides controlled visual access through the panel by using an LCD glass panel 2Z that can be made clear rather than translucent. With further reference to FIG. 1AA, a window 1AA provides visual and aural access through the panel with access being controlled by a tambour door 2AA. With reference to FIG. 1AB, a small window 1AB provides visual and aural access through the panel with access being controlled with a mini-blind shade 2AB. A window 1AC with a dot-pattern screen to provide limited visibility through the panel is illustrated in FIG. 1AC. Rather than replacing a full-size window, these windows allow for discreet communication between adjacent workspaces.
In addition to the access and/or privacy control arrangements described above, the modular accessory units may also comprise various seating units or the like that may be utilized to provide seating space for users when required, yet be storable in the partition when not required to conserve space. With reference to FIG. 1AD, a fold-out seat 1AD may be utilized to accommodate temporary visitors. The fold-out seat allows for group interactions without having to find an extra chair when working individually. A fold-out seat to accommodate group seating for temporary visitors is illustrated in FIG. 1AE. Such accessory units facilitate movement of objects and workflow off the desktop or worksurface and into the partition panel. Thus, a wide range of modular accessory units may be provided as required by a particular user.
With further reference to FIG. 2A, each partition frame 3 includes a pair of vertical side frame members 12, and upper and lower horizontal frame members 13, 14, respectively that extend between and rigidly interconnect the vertical side frame members 12 to form a generally quadrilateral perimeter. As described in detail in the above-referenced co-pending application Ser. No. 10/077,553, entitled PANEL SYSTEM, vertical side frame members 12 include a plurality of openings 15-18 for mounting cover panels 6, and horizontal frame members 13 and 14 include a plurality of openings 19 and 20. The openings 15-20 receive clips (not shown) on the cover panels 6 to thereby retain the cover panel 6 on the partition frame 3. The vertical side frame members 12 include a plurality of openings 21 (FIG. 5) that permit utility lines such as power and/or data lines to be fed horizontally through the vertical frame members 12 between adjacent partition frames 3. Similarly, upper frame member 13 includes openings 22 (FIG. 3), and lower frame member 14 includes openings 23 (FIG. 4) to permit vertical pass-through of power and/or data lines at the upper and lower edges, respectively, of the partition frame 3. A channel 24 (FIG. 5) extends along the upper horizontal frame member 13 to provide for horizontal lay-in of utility lines along the upper edge of the partition frame 3. Similarly, vertical side frame members 12 include vertically extending channels 25 (FIG. 3) to permit vertical routing of utility lines along the side edges of the partition frame 3. Upper horizontal cross member 13 includes a horizontal row of slots 27 (FIG. 2), and lower horizontal cross member 14 includes a row of horizontal slots 28. Vertical frame member 12 includes openings 39 and 40 that align with the horizontal row of slots in the intermediate cross member 26 to provide a continuous horizontal row of slots without “dead zones” at the vertical frame members 12 (see also FIG. 10). Vertical side frame members 12 each include a vertical row of slots 29. The rows of slots 27-29 may be utilized to support hang-on furniture units such as worksurfaces, binder bins, or the like.
Intermediate beams 4 each include a horizontal row of slots 26 for supporting hang-on furniture units. The intermediate beams 4 also include openings 19 and 20 for securing the cover panels 6. As discussed in more detail below, the openings 19 and 20 may also be utilized to secure smaller cover panels 10 to the partition frame 2 horizontally adjacent a modular accessory unit such as the flat screen display 7 illustrated in FIG. 1. With further reference to FIG. 6, each of the horizontal cross members 4, 13 and 14 include sets of openings 31 at regularly spaced intervals. In the illustrated embodiment, each set of openings 31 is repeated every six inches along each of the horizontal frame members 4, 13 and 14. The regularly spaced openings 31 define a plurality of discrete, serially adjacent mounting spaces 32. Openings 31 receive well-nuts or conventional self-tapping screws or the like to secure the modular accessory units to the partition frame 3. The mounting spaces 32 receive the modular appliance units 7, 8 and 9. For example, the power and data module 8 illustrated in FIG. 1 may have a width of twelve inches and take up two of the mounting spaces 32. Alternately, the modular appliance unit may have a width of twenty-four inches, such that the appliance unit takes up four of adjacent mounting spaces 32. Significantly, the modular appliance units can be mounted at a selected horizontal position in one or more of the mounting spaces 32, such that the horizontal position of the appliance unit can be selected to meet the needs of a particular user and/or application. Also, as described in more detail below, a single intermediate beam 4 may be mounted adjacent the frame members 13 or 14, such that a modular appliance unit may be mounted adjacent the upper or lower edge of the frame 3 by securing the appliance unit to the openings 31 in the intermediate beam 4 and frame member 13 or 14.
With further reference to FIGS. 7-9, each intermediate beam 4 includes a front face 33 with a horizontal row of slots 26, and openings 19 and 20 that receive clips to mount the cover panels 6 and/or smaller fill-in cover panels 10 and/or 11 illustrated in FIG. 1. As discussed above, each intermediate beam 4 includes a plurality of evenly spaced openings 31 for mounting the modular appliance units, and each intermediate beam 4 also includes a pair of hooks 34 at the opposite ends of the beam. With further reference to FIG. 10, vertical side frame members 12 include openings 35 that receive hooks 34 of the intermediate beams 4 to thereby retain the intermediate beams 4 on the vertical frame member 12. A flexible safety catch 36 is made of spring steel or the like, and is spot welded or otherwise attached to the intermediate beams 4 at the locations marked 37. The safety catch 36 includes a tab 38. During installation, during insertion of hooks 34 in openings 35, tab 38 contacts the vertical frame member 12, and flexes outwardly in the direction of the arrow “A”. As the intermediate beam 4 is shifted downwardly to engage the hooks 34, the tab 38 snaps into the opening 35. The tab 38 prevents upward shifting and inadvertent dislodgment of hooks 34 from the openings 35. To remove the intermediate beam 4, the flexible safety catch can be manually flexed, such that the tab 38 is disengaged from the opening 35, thereby permitting disengagement of hooks 34 from openings 35.
Each of the illustrated vertical frame member 12 includes a plurality of openings 35 at equal vertical intervals, such that one or more intermediate beams 4 can be positioned at a selected height on the partition frame 3. In the illustrated example, the vertical spacing between the pairs of openings 35 is 12.360 inches, such that the intermediate beams 4 can be positioned at 12.360 inch intervals on the vertical side frame members 12. Each vertical side frame member 12 includes a set of openings 35 spaced 12.360 inches from the upper horizontal frame member 13, and another set of openings 35 spaced twelve inches away from the lower horizontal cross member 14, such that an intermediate beam 4 can be mounted to the frame 3 12.360 inches away from upper frame member 13 and/or lower frame member 14. Upper frame member 13 and lower frame member 14 also include openings 31 (see also FIG. 2A) for mounting modular appliance units. Each set of four openings 31 in the frame member 13, 14 and intermediate beams 4 are spaced at six inch intervals, such that the appliance units can be positioned on six inch increments at any selected horizontal position. A horizontal row of mounting spaces 32 can be provided along the upper and/or lower portions of the frame 3 if required for a particular application. Thus, the horizontal location of the modular appliance unit can be varied by positioning the appliance unit in a selected space 32. Also, the intermediate beams 4 can be vertically positioned at a selected height, such that the modular appliance units can be readily mounted at selected vertical and horizontal positions.
FIG. 9B schematically illustrates the grid of appliance mounting spaces and cover panel configurations provided by the vertically adjustable intermediate beams and horizontally spaced mounting openings 31 in the intermediate beams and upper and lower frame members 13, 14. In FIG. 9B, each set of mounting openings 35 in the vertical frame members 12 are designated 35A, and each set of mounting openings 31 in the intermediate beams and frame members 13 and 14 are designated 31A. In the example of FIG. 9B, the intermediate beams are designated 4A, 4B and 4C. As discussed above, the sets of openings 31A are spaced at six inch horizontal intervals, designated S1, and the sets of openings 35A are spaced at 12.360 vertical increments, designated S2. The intermediate beams can be attached to selected ones of the sets of openings 35A, thereby providing a plurality of attachment locations 125 that may be utilized by connecting an intermediate beam to a selected set of openings 35A in the vertical frame members 12. The attachment locations 125 form a grid defining a plurality of mounting spaces 32A. Each of the mounting spaces 32A in the illustrated example has a width of six inches, and a height of 12.360 inches. As discussed above, the modular accessory units may have a width of six inches, twelve inches, eighteen inches, twenty-four inches, or any other multiple of six inches. In the example of FIG. 9B, a full width cover panel 6A has a height of S2, and extends across the entire width of the frame 3. A mounting space 32B having a width of twelve inches is provided between shorter width cover panels 11 and 10A immediately below the full width cover panel 6A. A second mounting space 32C having a twenty-four inch width is provided between cover panels 10B and 11. A full width cover panel 6B closes off the lower portion of the frame 3, and has a height of two times S2. The partial width cover panels 11, 10A and 10B may have a width of six inches, twelve inches, or any multiple of six inches to close off the gap or gaps along the side or sides of an appliance unit that is mounted in a mounting space 32. Thus, prefabricated partial width cover panels of six inches wide, twelve inches wide, eighteen inches wide, and each additional multiple of six inches can be provided, each having a height S2. Similarly, prefabricated full width cover panels 6 having heights S2, and each multiple of S2 may also be provided. Thus, the modular appliance units for a particular workspace or other such application can be selected to suit a user's needs. The horizontal and vertical location of the modular appliance units can also be selected, and the required number of intermediate beams are installed to the frame 3 at the desired vertical location(s). The required number and sizes of cover panels can then be selected and installed to close off the spaces that are not occupied by a modular appliance unit.
With reference to FIG. 11, power and/or data module 8 includes an upper flange 41, and a lower flange 42, each of which has at least two clearance openings 43. The openings 31 in intermediate beams 4 receive conventional well-nuts (not shown), and conventional threaded fasteners such as bolts or the like (also not shown) that extend through the clearance openings 43 in flanges 41 and 42 to thereby secure the power and/or appliance module in the mounting space 32. Alternately, self-tapping screws or other conventional fasteners may be received in openings 31 to secure the modular appliance units to the partition frame. Housing 44 of module 8 includes a front face 45 having openings 46 and 47 for mounting power receptacles 48 and data receptacles, respectively. A large opening 50 through the front face 45 permits pass-through of power and/or data lines from the interior space of the partition frame to the exterior. A bezel 67 may be releasably secured to the housing 44 and/or partition frame 3 to cover the housing 44 and close off opening 50. Bezel 67 includes an opening 68 to provide user access to power receptacles 48 and data receptacles 49. A pair of wire managers 69 extend around opening 68. Wire managers 69 are horizontally spaced from the front face 67A of bezel 67 such that utility lines such as power line 81 can be routed between a wire manager 69 and the face 67A of bezel 67.

This interference fit between the adjacent rollers 150 creates friction to control extension and retraction of the flat screen 92 and prevent excessive inadvertent movement thereof.
Instead of the left and right hand cover panel brackets 52 and 53 discussed above, an alternate embodiment 160 of the cover panel bracket may be utilized in both a left hand and right hand configuration (i.e., on either side of a modular appliance unit). Cover panel bracket 160 includes a front web 161, a pair of vertically extending side webs 162, an upper web 163, and a lower web 164 forming a shallow “shoebox” shape. Mounting openings 165-168 through the front web 161 recite mounting clips to retain cover panels 10 adjacent an appliance unit. The openings 165-168, and cover panel mounting clips are described in detail in the above-identified co-pending application Ser. No. 10/077,533, entitled PANEL SYSTEM, previously incorporated herein by reference. Side webs 162 are cut out at 172 to provide for routing of utility lines 175 therethrough to or from the adjacent appliance unit if required. With further reference to FIGS. 24-26, a second embodiment 180 of the bracket cover panel mounting bracket of FIGS. 22 and 23 is substantially the same as bracket 160, except that bracket 180 includes an enlarged cutout portion 181 through the front web 161 and side web 162 to permit lay-in of utility lines 175, such as data or power lines. A small strip 182 can be installed across the cutout 181 after the utility lines 175 are installed by placing the ends 183 of strip 182 in openings 184. The strip 182 provides a visual block between the edge of the cover panel 10 and the adjacent appliance unit, by extending across the gap between the appliance unit and the cover panel. An upwardly extending tab 185 similarly provides a light blocking function.
With further reference to FIGS. 27 and 28, bracket 160 may be installed between a pair of adjacent beams 4 by first inserting upwardly extending tab 169 into an opening 186 in lower surface 187 of the uppermost beam 4. The lower end 188 of bracket 160 is then rotated inwardly in the direction of the arrow “A” (FIG. 27) until the bracket 160 is vertically aligned in the position illustrated in FIG. 28. The bracket 160 is then shifted downwardly in the direction of the arrow “B” to engage the tabs 170 in openings 189 in upper side 190 of the lower beam 4. A plurality of threaded fasteners 191 are then inserted through the openings 174 (FIG. 23) in the lower web 164 of bracket 160 and into the corresponding openings 192 in the upper side 190 of the lowermost bracket 4. Threaded fasteners 191 may be self-tapping screws, well-nuts, or other such conventional fastener. During installation of fasteners 191, the installer may utilize the access opening 173 and cutouts 172 to provide access for the wrench, screwdriver, or the like. The fasteners 191 ensure that the bracket 160 is rigidly secured to the beams 4, without rattles or the like. Bracket 180 is installed in substantially the same manner as just described for bracket 160.
The modular appliance units of the present invention permit various such units to be mounted within the partition panel itself, thereby reducing the worksurface space that would otherwise be required for such units. The intermediate beams 4 can be positioned at various vertical heights, and the modular appliance units can be secured to a pair of intermediate beams 4 at the selected vertical position. Alternately, the modular appliance units may be secured to an upper frame member 13 and an intermediate beam 4, or, the modular appliance unit may be secured to an intermediate beam 4 and the lower horizontal frame member 14. Still further, the modular appliance units can be positioned horizontally in a selected mounting space 32. Accordingly, the present invention permits a wide variety of modular appliance units to be positioned at virtually any horizontal or vertical position within the partition panels 2 utilizing a common mounting arrangement. The common mounting arrangement permits the various types of modular appliance units to be interchanged/moved as required. Furthermore, because the modular appliance units are mounted at standard positions, and have standard sizes, fill in panels having standard widths and heights can also be provided to quickly fill in any gaps between the modular appliance units and the adjacent vertical frame members.
In the foregoing description, it will be readily appreciated by those skilled in the art that modifications may be made to the invention without departing from the concepts disclosed herein. Such modifications are to be considered as included in the following claims, unless these claims by their language expressly state otherwise.
